Which one of the following wavelength radiations may correspond to an X-ray?
Options
- A1 nm
- B10 nm
- C100 nm
- D300 nm
Correct answer
A. 1 nm
Step-by-step solution
The wavelength range of X-rays in the electromagnetic spectrum is generally from 0.01 nm to 10 nm (or 0.1 to 100 ). Among the given options, 1 nm falls well within the characteristic wavelength range of X-rays. Wavelengths from 10 nm to 400 nm correspond to the ultraviolet region. Answer: 1 nm
